In the MAC environment, during the development of HarmonyOS, the project runs to the simulator and reports the following errors:


compileSdkVersion and releaseType of the app do not match the apiVersion and releaseType on the device.

Operation steps.

I. If the HDC tool environment variables are not configured, configure them as follows, and skip this step if they have been configured.

1. Open Mac terminal and enter the following command to open the bash_profile file.

open .bash_profile

2. In the bash_profile file, configure the environment variables, here the PATH path, refer to your own sdk path, version is the version corresponding to Toolschains under API Version7 in my own SDK, the value is

export PATH=$PATH:/Users/tangkun/Library/HarmonyOS/Sdk/toolchains/{}

3. Save the configured environment variables and enter the following command in the open terminal.

source .bash_profile

4. Restart the development tool DevEco-Studio.

Second, the following is the operation of configured HDC environment variables:
In the terminal terminal of DevEco-Studio, enter the following command:

. /hdc shell

(Windows environment does not need the previous . /hdc shell)

Next, enter the following command in the terminal, but this time you do not need to enter . /, in terminal my Huawei emulator output 6.

getprop hw_sc.build.os.apiversion

This apiversion version number 6 is smaller than the version number 7 in my project’s build.gradle and project’s build.gradle, so it causes my project to run on this apiversion version 6 emulator with the following direct error.

The version numbers of entry and application in the build.gradle:
compileSdkVersion 7 and compatibleSdkVersion 7


1. lower the compileSdkVersion and compatibleSdkVersion version numbers in the build.gradle file of entry and application to 6.

2. Use an emulator with Api 7 for debugging.

Compilation error

Try to delete the ohos_config.json file in the project root directory, and then execute the “hb set” command, it still reports an error


Uninstall this one: pip3 uninstall ohos-build
and then execute three lines of code in the source code path

 pythom3 -m  pip install build/lite

 pythom3 -m  pip install ohos-build 

pip3 install build/lite

[Solved] Hongmeng compiles error: Unable to find the java component with apiVersion 4.

Problem phenomenon

	 > Cause: Unable to find the java component with apiVersion 4.
	 > Solution: 
		1.Open SDK Manager and download java.
		2.Alternatively, modify the compileSdkVersion settings in the project- and module-level build.gradle files. 


Modify the build.gradle file:

ohos {
    compileSdkVersion 4
    defaultConfig {
        compatibleSdkVersion 3

Change to:

ohos {
    compileSdkVersion 5
    defaultConfig {
        compatibleSdkVersion 3
